The new one is good. Just don’t rush, you’ll still need some time to figure out what can be changed. From the first view, on the login page you’d need to put “email” and “password” text on the login form a bit above or make them smaller. What about the main page, this solarized-like background doesn’t look good - the current one would be a good replacement for it. However, you can provide users a choice of which theme they want so they can change it anytime they want.
